Leonardo Dicaprio, the actor currently doing the promotional rounds for Baz Luhrmann's The Great Gatsby, is teaming up with Christie's for a charity auction next week to benefit environmental causes. Thirty-three pieces of art will go under the hammer on Monday (May 13, 2013) in New York and could raise $18 million.

"A lot of the works of this quality have never been at auction. We have what we believe are conservative estimates," Loic Gouzer, international specialist at Christie's and the head of the sale, said in an interview, "It is going to be the biggest one-time environmental fundraiser ever," he added. Amongst the pieces up for sale are Zeng Fanzhi's oil canvas The Tiger and Bharti Kher's The Skin Speaks a Language Not It's Own, on fibreglass. Another is Mark Grotjahn's Untitled (Standard Lotus No. II, Bird of Paradise, Tiger Mouth Face 44.01) an oil on cardboard mounted on canvas. Each other three works has a pre-sale estimate of $1.5 million to $2.5 million. Other artists include the Bristol artist Banksy, Peter Beard, Richard Prince and Elizabeth Peyton. "We explained that we wanted great works and they were very reactive because of the cause. The artists are very sensitive to the fact that we are destroying our planet," Gouzer said.

Leonardo DiCaprio's new movie The Great Gatsby hits theaters today. It has received mixed reviews from critics.
